PROBLEM 3.1 • The data obtained in a stress-strain test for a ceramic material are given in the table. The curve is linear between the origin and the first point. Graph the diagram and determine the modulus of elasticity and modulus of resilience. • Once the STRESS-DEFORMATION diagram is constructed, the elastic region is identified, that is, the region in which the curve is linear, in which a straight line occurs. Once this is done, the last point on the graph that belongs to the line is identified before it becomes non-linear. • Very well, having identified this coordinate (σ, ε) on the graph, it is easy to find the approximate modulus of elasticity of this ceramic material, because: • Eaprox = σ/ε (derived from Hooke's Law formula) • The modulus of resilience is given by calculating the area below the graph in which the curve is linear, that is, by the triangular area formed below the line, therefore: • ur = ε.σ/2 • Do you know what the resilience module is? • Explanation in the video. • • Hope you enjoyed the content!
